My bodged poly due to sloping ground

Took three weeks to put up due to foundations from previous buildings comprising the hardest stone I have ever encountered. Still have a numb finger from the drilling vibration. The away side is held down by a raised bed due to the ground dropping away. The kit blurb suggested it could be put up in 2 days.... Uh HUH.....NOT.

The solar panels are driving tomato hydroponic systems which so far seem to be producing the best plants.

My wife has a trial running with plants in the soil, some in normal grow bags and the two solar units. The solar plants are looking a lot stronger but we intend weighing the fruit to prove the results.

From memory the solar panels put out 10 to 12 watts and obviously with the variation in sun strength the power varies as does the consequent output of dripping into the plants. We found that this meant the plants are being watered in harmony with the weather. Now the plants are mature and starting to grow their fruit the roots are into the nutrient tank and the pumps are redundant really but no doubt the watering from the top is still beneficial.
